Findings: Sagittal and axial T1, axial T2, coronal and sagittal T2 FAIR and post gadolinium axial images through the brain were performed. Numerous foci of periventricular, periatrial and deep white matter signal abnormalities. There is diffuse foci of parenchymal trophy. There are additional foci of signal changes within the subcortical white matter of the bilaeral hemispheres. Also with interval development of several new lesions. Following contrast administration, multiple enhancing lesions are noted in the right frontal and parietal lobes.
